The case
Interview preparation is easy to scatter across notes, problem lists and disconnected tutorials. PreppUp brings the reading, practice and review into one workspace. A problem has explanations and multiple solutions; a topic leads straight to a quiz; a plan brings the next task into view.
- Write and run the answer. Python executes in the browser, alongside a SQL playground for query practice.
- Go beyond one track. Coding rounds sit beside architecture, cloud, AI and data engineering topics.
- Keep a learning rhythm. Daily plans, review queues, notes and mock interviews make progress visible.
- Take it with you. The installable web app supports offline study; signing in syncs progress across devices.
